Hydro Multi-E 1

1. Introduction

Grundfos Hydro Multi-E booster systems are designed for the transfer and pressure boosting of clean water in places such as

• blocks of flats

• hotels

• industry

• hospitals

• schools.

Grundfos Hydro Multi-E booster systems consist of two to four Grundfos CRE, CRIE pumps or two or three CME-A, CME-I pumps connected in parallel and mounted on a common base frame provided with all necessary fittings.

As standard, the Hydro Multi-E is supplied with the following:

• base frame

• pumps

• suction and discharge manifolds

• pressure switch as dry-running protection

• one or two discharge-pressure sensors, depending on pump size

• non-return valves, one per pump

• isolating valves, two per pump

• pressure gauge

• diaphragm tank

• breaker box.

On delivery, the Grundfos Hydro Multi-E booster system is factory-tested and ready for operation.

Fig. 1 Hydro Multi-E with three single-phase pumps

The Hydro Multi-E is available in two versions, depending on pump size.

Hydro Multi-E, 0.37 to 2.2 kW

The pumps incorporated in this Hydro Multi-E system are fitted with the new-generation MGE motors which are permanent-magnet motors with a high-efficiency frequency converter. The motors ensure an even higher efficiency than the previous version of the booster system. The MGE motors have a total efficiency which exceeds the IE4 Super Premium Efficiency level defined for fixed-speed motors.

The Hydro Multi-E with pumps in this range offers additional functions:

• multi-master function

• pipe-filling function

• predefined setpoint

• external setpoint influence

• limit-exceeded function.


The Hydro Multi-E with pumps in this range is fitted with MGE motors which are asynchronous motors with built-in frequency converter. These motors are IE3-compliant as standard.

Benefits

Plug-and-pump solution

The Hydro Multi-E is supplied as a complete preassembled system mounted on a base frame. The only task left is to connect the pipes and the power supply.

User-friendliness

The Hydro Multi-E is a highly intelligent booster system which is capable of controlling two to four speed-controlled pumps in cascade. The Hydro Multi-E is one of our most simple booster systems to start up and operate. It has only two buttons for complete control of the system. Alternatively, you can use Grundfos GO Remote for setup and control.

Perfect constant-pressure control

The speed-controlled pumps are perfectly controlled and adjusted by the PI controller of the Hydro Multi-E to deliver the correct pressure at the required flow.

Reliability

The Grundfos CRE, CRIE and CME pumps are known for their reliability and long life. The PI controller is protected inside the pump and this has proven to be a very reliable solution.

Multi-master function (0.37 to 2.2 kW)

All pumps that have a discharge-pressure sensor connected are capable of taking control of the entire booster system. This means that the system will continue to operate as a booster system even if one or more of the pumps or sensors are unavailable. Compared to systems with only one sensor, this makes the Hydro Multi-E an extremely reliable solution.

Redundant sensor (0.37 to 2.2 kW)

No system is more reliable than the weakest component. In connection with booster systems, it is common to rely on only one pressure measurement. However, that makes the operation extremely dependent on one single sensor. On the Hydro Multi-E, we do not depend on one sensor (single point of failure) as the booster system is supplied with two discharge-pressure sensors as standard.

Tested and ready to use

Before delivery, all Hydro Multi-E systems are carefully tested to Grundfos standard, i.e. pressure-tested and tested for full functionality.

Low energy consumption

The Hydro Multi-E ensures low energy consumption through speed-controlled pumps, automatic cascade control of the pumps and highly efficient low-flow operation. The highly efficient motors and pumps also contribute to the overall high efficiency of the Hydro Multi-E system.

Hydro Multi-E 3

3. Construction

Fig. 4 Hydro Multi-E with two CRE, CRIE pumps

Fig. 5 Hydro Multi-E with two CME pumps

* Only systems with CRE, CRIE pumps are available with four pumps.

System componentsThe Hydro Multi-E has a base frame fitted with the following components:

Components fitted on suction side

• a suction manifold

• an isolating valve per pump

• a pressure switch for dry-running protection.

Components fitted on discharge side

• a discharge manifold

• a non-return valve per pump

• an isolating valve per pump

• a pressure gauge

• one or two discharge-pressure sensors, depending on pump size

• a diaphragm tank.

The Hydro Multi-E is fitted with a breaker box for switching the power supply on and off.

MaterialsThe Hydro Multi-E incorporates the well-known high-quality Grundfos CRE, CRIE or CME pumps. However, the quality extends beyond the pumps. As standard, the Hydro Multi-E is supplied with stainless-steel manifolds (EN 1.4301) manufactured using an extrusion method that creates a smooth surface from the connecting pipe to the manifold. This minimises the risk of stagnant water and reduces noise and friction loss.

Note: In some regions, galvanised-steel manifolds are also available. Contact Grundfos for further information.

4. Installation

Mechanical installationA Hydro Multi-E booster system must be installed in a well-ventilated room to ensure sufficient cooling of the pumps. Hydro Multi-E is not suitable for outdoor installation.

Place the booster system in such a way that there is sufficient clearance around it for the operator to be able to work freely.

Enclosure class: IP54.

Insulation class: F.

Motor coolingTo ensure adequate cooling of motor and electronics, the following must be observed:

• Place the Hydro Multi-E in a well-ventilated room.

• The temperature of the cooling air must not exceed 40 °C.

• Motor cooling fins, holes in fan cover and fan blades must be kept clean.

PipeworkThe pipes connected to the booster system must be of adequate size. Fit expansion joints in the suction and discharge manifolds to avoid resonance. The pipes are to be connected to the suction and discharge manifolds.

The booster system should be tightened up prior to startup.

We recommend to fit pipe supports both on the suction and the discharge side.

The booster system should be positioned on an even and solid surface, for example a concrete floor or foundation. If the booster system is not fitted with vibration dampers, it must be bolted to the floor or foundation.

Fig. 8 Pipework

Expansion joints and pipe supports are not included in a standard booster system.

Electrical installationThe electrical connection and protection should be carried out in accordance with local regulations.

• The Hydro Multi-E must be correctly earthed.Note: 4.0 to 5.5 kW motors must be connected to especially reliable/sturdy earth connections due to an earth leakage current above 3.5 mA.

• The pumps require no external motor protection.The motors incorporate thermal protection against slow overloading and blocking (IEC 34-11: TP 211).

• When the pumps are switched on via the power supply, they will start after approx. 5 seconds.

Note: The number of starts and stops via the power supply must not exceed four times per hour.

If the system is supplied with a breaker box for wall mounting, the cabinet must be mounted in accordance with local regulations.

Hydro Multi-E5

Building management system (BMS)Communication with the Hydro Multi-E is possible even though the operator is not present near the Hydro Multi-E. Communication is enabled by having connected the Hydro Multi-E to a building management system allowing the operator to monitor and change control modes and setpoint settings of the Hydro Multi-E.

The communication interface between the Hydro Multi-E system and a central building management system varies, depending on pump size.


These booster systems can communicate with external systems via a Grundfos communication interface module (CIM) that can be fitted in the pumps. This means that no external communication interface is required.


These booster systems can communicate with external systems via an external Grundfos communication interface unit (CIU).

Fig. 13 Structure of a building management system

Control modes

Constant-pressure modeHydro Multi-E is suitable for applications where you want to control the pressure on the discharge side of the booster system, irrespective of the flow.

Signals of pressure changes in the piping system are transmitted continuously from the sensor to the Hydro Multi-E. The pump responds to the signals by adjusting its performance up or down to compensate for the pressure difference between the actual and the desired pressures. As this adjustment is a continuous process, a constant pressure is maintained in the piping system.

In constant-pressure mode, the Hydro Multi-E maintains a preset pressure on the discharge side of the booster system, irrespective of the flow.

Fig. 14 Constant-pressure mode

To meet the flow requirements of the system, the Hydro Multi-E continuously adjusts the number of running pumps.

Hydro Multi-E6

Description of functions

Automatic cascade controlCascade control ensures that the performance of the Hydro Multi-E is automatically adapted to the consumption by switching pumps on or off. The system thus runs as energy-efficiently as possible with a constant pressure and only the number of pumps required.

Dry-running protectionThis function is very important as dry running may damage bearings and shaft seals.

The inlet pressure of the system or the water level in a possible tank on the inlet side is monitored. If the inlet pressure or the water level becomes too low, all pumps will be stopped.

Level switches, pressure switches or analog sensors signalling water shortage at a set level can be used. Note: Analog sensors are only available for 0.37 to 2.2 kW systems.

Pump alternationThis function ensures that the operating hours are distributed evenly on the pumps over time.

Limit exceeded 1 and 2


The limit-exceeded function is used for monitoring one or two values/inputs. The function enables different inputs to activate various outputs and alarms/warnings when the signal input has exceeded predetermined limits. The purpose of this function is to monitor parameters which are central for the application. This will enable the pumps to react to possible abnormal operating conditions.

The function can for instance be used for monitoring the following:

• the inlet pressure if an inlet pressure sensor is connected

• the drinking water temperature if a temperature sensor is connected.

Multi-master function


All pumps that have a discharge-pressure sensor connected can function as master pump and control the system. As standard, the Hydro Multi-E is supplied with two discharge-pressure sensors.

As standard, the pump with the lowest number will be the master pump. From factory, the master pump is marked with number 1.

If the master pump is switched off or stopped due to an alarm, one of the other pumps will automatically take over the control of the system. Thereby, the reliability is increased and stop of operation is prevented.

As an option, the system can be supplied with only one discharge-pressure sensor. In that case, the system will stop if the pump or sensor fails.

The system can also be fitted with sensors on all pumps for maximum reliability.

Number of starts per hourThis function limits the number of pump starts and stops per hour.

Each time a pump starts or stops, the system will calculate when the next pump is allowed to start or stop in order not to exceed the permissible number of starts per hour.

This function always allows pumps to be started to meet the requirement, but pump stops will be delayed, if necessary, in order not to exceed the permissible number of starts/stops per hour.

Stop functionThe stop function checks the flow regularly by reducing the speed for a short time, thus checking the change in pressure. If there is no or a small change in pressure, the pump will detect a low flow.

When the pump detects a low flow, the speed will be increased until the stop pressure (actual setpoint + 0.5 x ΔH) is reached and the pump stops. When the pressure has fallen to the start pressure (actual setpoint - 0.5 x ΔH), the pump will restart.

ΔH indicates the difference between start and stop pressures.

Fig. 15 Start and stop pressures

ΔH is factory-set to 10 % of actual setpoint. ΔH can be set within the range from 5 to 30 % of actual setpoint.

The Hydro Multi-E is fitted with a diaphragm tank of an appropriate size to accommodate the operation in low flow. The precharge pressure must be 0.7 x actual setpoint.

Pipe-filling function


This function ensures a soft start of systems with empty pipework.

The function has two phases:

1. The pipework is slowly filled with water.

2. When the pressure sensor of the system detects that the pipework has been filled with water, the pressure is increased until it reaches the setpoint. See fig. 16.

Fig. 16 Filling and pressure build-up phases

The function can be used to prevent water hammer in high-rise buildings with unstable power supply or in irrigation systems.

External setpoint influence


This function is used for influencing the setpoint via an external setpoint signal. The value of the external setpoint signal is used in a formula calculating a "new" setpoint, i.e the actual setpoint. The function is often used for adjusting the setpoint depending on an external input from a Grundfos VSF flowmeter.

Predefined setpoint


This function is used for changing between predefined setpoints via digital input signals. This means that the operator can easily change setpoint by pressing a button. Due to the combination of digital inputs, up to three predefined setpoints can be configured.

Overview of inputs/outputs

Usage of the inputs and outputs


• Two digital inputsThe digital inputs can be used for remote control of the following functions:

– external stop

– setting the pumps to operation on the max. curve

– setting the pumps to operation on the min. curve

– dry-running protection, pulse flow, flow switch.

• Two analog inputsThe analog inputs can be used for feedback sensors, setting of setpoint influence or monitoring of analog values with the limit-exceeded function.

• Two digital outputsThe digital outputs can be used for sending a signal regarding pump operating status:

– ready

– fault

– operating

– running

– limit exceeded.


• One digital inputThe digital input can be used for remote control of the following functions:

– external stop

– dry-running protection.

• One analog inputThe analog input can be used for feedback sensor.

• One digital outputThe digital output can be used for sending a signal regarding pump operating status:

– ready

– fault

– operating.

7. Sizing

To ensure that the system is operating as efficiently as possible, it is important that the system is sized so that the performance meets the requirements of the application.

Note: Local legislation must always be taken into account.

FlowThe total consumption and the required maximum flow rate depend on the application in question. The required maximum flow can be calculated by means of the table below which is based on statistical data.

* fd: Maximum consumption factor per day.** ft:Maximum consumption factor per hour.

Hydro Multi-E 7

HeadThe required discharge pressure, pset, of Hydro Multi-E can be calculated from the following formula:

Key

Fig. 17 Calculation of required discharge pressure

Example

Inlet pressureIf the system has a positive inlet pressure, it must be taken into consideration to ensure that the total pressure in the system does not exceed the maximum operating pressure of the system.

Optional equipment and accessoriesThe Hydro Multi-E can be fitted with equipment for communication, dry-running protection, emergency operation, etc.

See sections Optional equipment, page 42, and Accessories, page 44, for more details.

pset = ptap(min) + pf + (hmax/10.2) + pfmpboost = pset - pin(min)

pset = Required discharge pressure [bar].ptap(min) = Required minimum pressure at the

highest tapping point [bar].pf = Total pipe friction loss [bar].hmax = Height from booster discharge port to

highest tapping point [metres].pin(min) = Minimum inlet pressure [bar].pboost = Required boost [bar].pfm = Friction loss in manifolds, isolating valves

and non-return valves.T

Example: How to select a system• A head of 45 m is required.

The pump type best meeting this specification is found by means of the y-axis (for example CRE, CRIE 10-6). Draw a rightward, horizontal line from the head required.

• A flow rate of 18 m3/h is required.Now draw an upward, vertical line from the specified flow. The intersection of the two lines gives the number of pumps required for the system (two CRE, CRIE 10-6).

Only systems whose operating ranges lie within the hatched area of the example should be selected.

8. Performance curves and technical data

Curve conditionsThe guidelines below apply to the curves on the following pages:

• Curve tolerance: ISO 9906:1999, Annex A.

• Test liquid: airless water at a temperature of +20 °C.

• The curves apply to the following kinematic viscosity: υ = 1 mm2/s (1 cSt).

• The QH curves apply to fixed speeds of 3480 min-1 (60 Hz). Note: The actual speed will in most cases deviate from the above-mentioned speeds. So for realistic curves, please refer to WebCAPS where the pump curves include the characteristics of the selected motor and therefore show curves at actual speeds. In WebCAPS, it is also possible to adjust the curves depending on the density and viscosity.

• The conversion between head H (m) and pressure p (kPa) applies to a water density of ρ = 1000 kg/m3.

Hydro Multi-E9

9. Optional equipment

All optional equipment, if required, must be specified when ordering the Hydro Multi-E booster system, as it must be fitted from factory prior to delivery.

Dry-running protection


As standard, the Hydro Multi-E is fitted with a pressure switch as dry-running protection. The switch is fitted to the suction manifold.

Optionally, the system can be supplied with a level switch instead of the pressure switch. This is common if the booster system is supplied from a break tank.

As an alternative, the system can be factory-fitted with inlet-pressure sensors for dry-running protection.

The benefit of this option is that it is easier to adjust the trigger level of a sensor and that the inlet pressure can be monitored with Grundfos GO Remote and via a connected BMS system (CIM module required).

To ensure that the system is properly protected against dry running, an inlet-pressure sensor must be connected to the pumps that can potentially act as master. This means that every pump that has a discharge-pressure sensor connected should also have an inlet-pressure sensor connected.

The sensors are available from 0 to 1 bar and from 0 to 6 bar.

Note: If a sensor is used for dry-running protection, it requires a Grundfos GO Remote to adjust the trigger level of the sensor.

If the system is fitted with two discharge-pressure sensors (standard), the two inlet-pressure sensors are fitted in the suction manifold with a drain valve and a T-piece. The drain valve allows for test of the dry-running function.

Fig. 20 Two inlet-pressure sensors fitted to T-piece

If the system is configured with more than two discharge-pressure sensors, a special connecting piece with a built-in air vent is used. The connecting piece is fitted to a drain valve.

Fig. 21 Installation of more than two sensors

Note: The standard pressure switch normally supplied with the system is removed when the system is fitted with inlet-pressure sensors for dry-running protection.

Emergency operation


The emergency operation feature ensures the supply of water in these cases:

• sensor fault

• controller fault (pump 1).

If emergency operation is required, this must be stated when ordering. Then two or three pressure switches will be fitted to the discharge manifold prior to delivery.

Hydro Multi-E 9

Non-return valve on suction sideFor suction-lift operation, the non-return valve can be moved to the suction side. This is often used in combination with a foot valve if the system is drawing water from a tank.

No dry-running protectionThe Hydro Multi-E can be supplied without dry-running protection.

Note: We always recommend you to protect your system against dry running.

Discharge-pressure sensor on each pump


As standard, the Hydro Multi-E is fitted with two discharge-pressure sensors. If required, the system can be fitted with a sensor on each pump. The benefit is that all pumps in the system can act as master pump and control the system.

When more than two discharge-pressure sensors are connected, the sensors are fitted in a special connecting piece with a built-in air vent in the top. The connecting piece is fitted to a drain valve.

No redundant sensorThe system can be supplied with only one discharge-pressure sensor.

Note: This disables the multi-master function.

Wall-mounted breaker boxA breaker box for wall-mounting and five metres of flexible cable are supplied with the booster system. With this option the breaker box does not necessarily have to be installed in the same room as the booster system. The pumps are wired with five metres of cable, but not wired into the breaker box. The reason for not connecting the cables in the breaker box is to give the customer the opportunity to adjust the cable length to his need.

Left-side breaker boxAs standard, the breaker box is mounted on the right side of the system. As an alternative, the system can be supplied with the breaker box mounted on the left side.

CIM communication interface modules


Fig. 23 Grundfos CIM communication interface module

The CIM modules enable communication of operating data, such as measured values and setpoints, between the Hydro Multi-E and a building management system.

Note: CIM modules must be fitted by authorised personnel.

The CIM module enables transfer of data such as:

• operating mode

• setpoint

• control mode

• warnings and alarms

• power/energy consumption.
